Hello. My name is Maciej I am a Python developer. I have big experience in creating store restock monitors (Supreme, adidas, Yeezy, OBD, Off---white and many others) I can write shopify restock monitor for you that checks both xml and json and can use keywords. Also I created a nike/launch monitor too. Monitors can send notification to discord/slack/twitter/email/sms or what ever else you wish.
Looking forward to hear back from you
Kind Regards
